The technique is presently restricted to use with SMPS which have magnetics designed to operate in discontinuous mode. This proportional inductance drive (PID) is so named to describe the circuitry used for implementation. The PID provides three important base drive functions in one simple circuit. It provides forward base current proportional to collector current during on time. It provides reverse base current proportional to collector current during storage time. It provides reverse bias clamping for base-emitter voltage. All three functions are performed by one simple magnetic circuit which is easily driven by most of the commercially available PWM control chips.","PeriodicalId":132848,"journal":{"name":"INTELEC '84 - International Telecommunications Energy Conference","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1984-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121415351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A software package to be used with CAD circuit simulation analysis programs (such as SCAMPER, ASTAP, or SUPER*SCEPTRE) allows the designer to quickly create specific device models using readily available information on manufacturer's data sheets. This package includes a library of generic device models, and a parameter-generating program for each type of device to generate operational parameters needed by the generic models in a circuit simulation. A few examples of device models developed in this way are presented, with a brief description of how the operational parameters are generated from the very limited information given on data sheets. Good agreement with actual device characteristics (both stacic and transient) are obtained. This approach also makes creating a current library of specific devices very easy, and appears to be ideal for starting a power circuit simulation program.","PeriodicalId":132848,"journal":{"name":"INTELEC '84 - International Telecommunications Energy Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1984-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129959604","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consisting of a large battery plant for 48 V or 60 V dc with a suitable charging rectifier, this fundamental power source maintains the secure operation of central offices or PBXes, independent of mains supply fluctuations. Considerable volume and cost are the well known disadvantages of such power systems. While the battery producers have been developing the new generation of sealed cells, designers of rectifiers have been investing remarkable efforts in reducing the size of large current range units. It is only the success on both fields that enables a reasonable integration of complete uninterruptible power supply within the communication system. The best way of avoiding the very large magnetic components used in SCR of ferro resonant controlled rectifiers, is to apply the switched mode technology. This paper is to present our latest achievements on the field of SM charging rectifiers for three-phase off-line operations. Power range up to over 8 kW and high efficiency of about 95 % will be discussed as the main features of the new power conversion system.","PeriodicalId":132848,"journal":{"name":"INTELEC '84 - International Telecommunications Energy Conference","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1984-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116512143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It will then become clear that what seems to be an extravagant use of conductors is really the result of a trade-off between marginal battery and cable costs. A method is described for calculating the most economical distribution voltage drop. Since a large proportion of telecommunications equipment operates at a nominal -48 volts this paper will limit itself to a discussion of 48 volt distribution. Although there has been phenomenal technological development in telecommunications equipment the technology of distribution has not changed; we still use copper or aluminum conductors. However, there have been changes in system voltage limits and power plant configuration as a result of the technological change in load equipment. Also, distribution design has been re-examined.","PeriodicalId":132848,"journal":{"name":"INTELEC '84 - International Telecommunications Energy Conference","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1984-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123975342","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To properly and adequately support this user community, communications from the Space Station to Earth stations will be necessary. The various data forms expected include video and audio and are expected to reach 300 Mbps. The video portion, especially, requires a large bandwidth and high power for transmission. In general, the housekeeping power levels for the Space Station subsystems will be much higher than in previous programs. The expected power levels for the Space Station range from 75 kW to 300 kW for both housekeeping and users/payloads, a large portion of which is telecommunications. Because of this high power level, it becomes impractical to continue the current use of a 28-V dc bus for power distribution. The current concept to supplant this low-voltage bus system is to go to a higher voltage and thereby to increase performance and efficiency. The two technology options available are high-voltage dc and high-voltage, high-frequency ac. Up to approximately 100 kW of bus power, both technologies are competitive. At higher power levels, ac is increasingly attractive. As part of the Space Station effort at the NASA Lyndon B. Johnson Space Center (JSC), a high-voltage, high-frequency ac system has been studied and a design concept generated. This system has a 200-V, 20-kHz primary bus.","PeriodicalId":132848,"journal":{"name":"INTELEC '84 - International Telecommunications Energy Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1984-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129064840","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
